First, create a database in TDengine to store Prometheus data:

```sql
CREATE DATABASE prometheus_data;
```

Configuring Prometheus is done by editing the Prometheus configuration file `prometheus.yml` (default location `/etc/prometheus/prometheus.yml`).

#### Configure Third-Party Database Address

Set the `remote_read url` and `remote_write url` to point to the domain name or IP address of the server running the taosAdapter service, the REST service port (taosAdapter defaults to 6041), and the name of the database you want to write to in TDengine, ensuring the URLs are formatted as follows:

- remote_read url: `http://<taosAdapter's host>:<REST service port>/prometheus/v1/remote_read/<database name>`
- remote_write url: `http://<taosAdapter's host>:<REST service port>/prometheus/v1/remote_write/<database name>`

#### Configure Basic Authentication

- username: \<TDengine's username>
- password: \<TDengine's password>

#### Example configuration of remote_write and remote_read in the prometheus.yml file

```yaml
remote_write:
  - url: "http://localhost:6041/prometheus/v1/remote_write/prometheus_data"
    basic_auth:
      username: root
      password: taosdata

remote_read:
  - url: "http://localhost:6041/prometheus/v1/remote_read/prometheus_data"
    basic_auth:
      username: root
      password: taosdata
    remote_timeout: 10s
    read_recent: true
```
